摘要

提出了两种基于形态学滤波和特征空间判别分析的人脸识别方法。这两种方法都计算了每个人脸样本的形态轮廓(MP)。MP包含人脸图像的上下文信息。此外,FSDA是2015年引入的一种新的特征提取方法,它提取的特征具有最小的冗余信息和最大的类判别信息。第一种方法仅使用FSDA获得的MP的第一分量,而第二种方法通过重建使用所有开闭滤波器提供的整个图像。通过FSDA对滤波后的图像进行降维。然后,将特征馈送到最近邻分类器。最后利用决策融合规则找到每个测试人脸图像的标签。在ORL和Yale人脸数据库上的实验结果表明,与一些流行的和最先进的人脸识别方法相比,所提出的方法具有优越的性能。

Face recognition using morphological profile and feature space discriminant analysis
Two face recognition methods based on morphological filters and feature space discriminant analysis (FSDA) are proposed in this paper. Both the proposed methods calculate the morphological profile (MP) of each face sample. The MP contains the contextual information of the face image. Moreover, FSDA, which is a novel feature extraction method introduced in 2015, extracts features with minimum redundant information and maximum class discrimination one. The first proposed method just uses the first component of MP obtained by FSDA, while the second proposed method uses the whole images provided by all opening and closing filters by reconstruction. The dimensionality of each filtered image is reduced by FSDA. Then, the features are fed to a nearest neighbor classifier. Finally the decision fusion rule is used to find the label of each test face image. The experimental results on ORL and Yale face databases show the superior performance of the proposed methods compared to some popular and state-of-the-art face recognition methods.
